show_graph - displays a graph

### Calling Sequence

  `nw = show_graph(g,[smode,scale])`
  `nw = show_graph(g,[scale,winsize])`

### Parameters

- `g`: graph list
- `smode`: string, mode value
- `winsize`: row vector defining the size of edit_graph window
- `scale`: real value, scale factor
- `nw`: integer

### Description

`show_graph` displays the graph `g` in the current edit_graph window. If there is no current edit_graph window, a edit_graph window is created. The return value `nw` is the number of the edit_graph window where the graph is displayed.

If the optional argument `smode` is equal to the string 'rep' or is not given and if there is already a graph displayed in the current edit_graph window, the new graph is displayed instead.

If the optional argument `smode` is equal to the string 'new', a new edit_graph window is created. In this case, if the optional argument `winsize` is given as a row vector `[width height]`, it is the size in pixels of edit_graph window. The default is `[600,400]`.

The optional argument `scale` is the value of the scale factor when drawing the graph. The default value is 1.

    he=[2 10 3 5 7 4 2 4 6 8 6 9 7 7 11 15 12 13 9 10 14 11 16 1 17 14 15];
    g=make_graph('foo',1,17,ta,he);
    g('node_x')=[283 163 63 57 164 164 273 271 339 384 504 513 439 623 631 757 642];
    g('node_y')=[59 133 223 318 227 319 221 324 432 141 209 319 428 443 187 151 301];
    show_graph(g,2);
    show_graph(g,0.5);
    show_graph(g,1);
